    Thereafter, uranium and thorium concentrations in Fruitful were measured by NAA and revealed that Fruitful contained 94-141 ppm uranium and 127-506 ppm thorium. Therefore, this noticeable amount of uranium and thorium in Fruitful should be taken in consideration during any mining attempt of the placer minerals present in Cox's Bazar beaches.
